What is Selzentry?

Selzentry can be described as an antiviral drug that blocks certain viral cells from multiplying within your body.Selzentry helps to stop human immunodeficiency virus (HIV) from multiplying inside your body.

Selzentry is a component of other medicines in order to manage CCR5-tropic HIV type 1. This is a virus that can lead to acquired immune deficiency syndrome (AIDS). Selentry is not an answer to HIV and AIDS.Selzentry can be used by adults and children who weigh at least 4.4 kilograms (2 kg).


If you suffer from severe kidney problems, then you might not be able to take Selzentry in the event that you take other medications. Discuss with your doctor any other medications you're taking.

Selentry can cause liver issues. Do not take this medication, and seek medical attention immediately if you experience an acute reaction to drugs that could harm the liver. Symptoms may include itching or rash, vomiting, upper stomach pain, dark urine, and jaundice (yellowing of the eyes or skin).

Prior to use this drug

If you have a severe or end-stage kidney disease, you might not be able to take Selzentry if you take specific medications, like antifungal and antibiotic medications, some blood pressure or heart medications, St. John's wort, as well as certain medications to treat hepatitis and tuberculosis. Tell your doctor about all medications you are currently taking.

To be sure Selzentry is appropriate for you, ask your doctor if you previously had:

  • Renal disease (or if you're taking dialysis);
  • Liver disease, specifically hepatitis B and C;
  • Heart disease
  • Low blood pressure.

Maraviroc impacts your immune system and could increase the chance of contracting cancer or infections. Consult your physician about this possibility.

Inform your doctor if you are pregnant, and make sure you use the correct medications to manage your infection. HIV could be transmitted to your baby if the virus is not managed during pregnancy. Your name might be recorded on a registry in order to monitor the effects of antiviral medication on your baby.

Women who have HIV or AIDS are not allowed to give birth to a baby. Even if the baby is born with no HIV or AIDS, the virus could be transmitted to your baby by the milk you give it.Selzentry is not recommended for premature babies or a child who has a weight of less than 4.4 kilograms (2 kg).
